Examining the Evolving Properties of Dwarf Galaxies Using the Hydrodynamical Adaptive Refinement Tree Code

Kenza Arraki, Ohio Supercomputer Center

Usage Details

Kenza Arraki is studying how galaxies change throughout cosmic time. Her research is focused on understanding how baryonic physics impacts the formation and evolution of dwarf galaxies. Observations and numerical simulations continue to produce different results on the abundance, structural properties, and stellar mass assembly history of dwarf galaxies. Kenza uses the hydrodynamical Adaptive Refinement Tree code (hydroART) to investigate how updated models for star formation and stellar feedback change the evolving properties of dwarf galaxies. In this research project, she will produce a large sample of high-resolution dwarf galaxies in a cosmological context. Using these simulated dwarf galaxies, Kenza will compare their structural, stellar, and gaseous properties to those of observed galaxies. This will enable the astronomical community to better understand which physical processes are the dominant components driving dwarf galaxy evolution.
